Abstract

The invention discloses a whole vehicle energy distribution method, a system and an electric vehicle, comprising: setting energy use priority from high to low, sequentially including safety requirement, driving requirement and comfort requirement; Detecting an entire vehicle mode, wherein when the entire vehicle mode is a mileage mode, the required power for controlling the comfort requirement isless than a first preset value, wherein the entire vehicle mode comprises a mileage mode and a normal mode; obtaining The maximum discharge power of the power battery, and the allowable power of eachenergy use priority according to the maximum discharge power; Controlling the subsystem in the whole vehicle system to work according to the permissible power. Adding A mileage mode in the whole vehicle mode, According to the whole vehicle mode, the energy distribution scheme of the whole vehicle is made. In the low temperature limit environment, if the driver pursues the long mileage, the required power of the comfort demand is limited, which not only saves the electric energy of the power battery, but also can more flexibly carry out the energy distribution according to the driver's demand,and improve the driver's driving experience.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a vehicle energy distribution method, system and electric vehicles. Background technique [0002] With the depletion of various non-renewable resources and the increasing environmental pollution, in order to reduce energy consumption and pollution, the development of new energy vehicles has become the direction of the global automotive industry. At present, pure electric vehicles, which use power batteries as the main power source, have quickly become the main development targets of major car companies due to their advantages of zero emissions and low pollution. As the energy storage device of pure electric vehicles, the power battery provides energy for driving the whole vehicle on the one hand, and provides energy for high-voltage accessories such as PTC (Positive Temperature Coefficient, heater), compressor, etc., and low-voltage accessories such as wipers, lights, DVD, etc. ...
